Her family just keeps expanding!

Real Housewives of Atlanta star Kim Zolciak is pregnant with her fifth child, In Touch reports.

The wig-wearing blonde gave birth to her son Kash Kade a mere nine months ago!

"Kim and Kroy are so excited to be pregnant again. She's been trying to keep it quiet - she didn't realize she's showing as much as she is," a source tells the mag.

This will be the third child for the reality star and her Atlanta Falcons beau Kroy Biermann. Miss Zolciak also has daughters Brielle, 16, and Ariana, 11, from previous relationships.

Congrats Miss Z!
